Step-by-step explanation:

set f(x) equal to y

y = 19/ x^3

swap x and y

x = 19/y^3

make y the subject

xy^3 = 19

y^3 = 19/x

[tex]y = \sqrt[3]{ \frac{19}{x} } [/tex]

then just replace y with f^-1(x)

[tex]f(x) = \sqrt[3]{ \frac{19}{x} } [/tex]

hope this helped! have a good day ~ •lipika•

The inverse of the function F(x) is:

          [tex]\sqrt[3]{\dfrac{19}{x}}[/tex]

We are given a rational function F(x) as:

[tex]F(x)=\dfrac{19}{x^3}[/tex]

The steps to find the inverse function of a given function f(x) are as follows:

1.   Put f(x)=y

2.  Interchange the value of x and y

3.  Solve for y.

Hence, we find the inverse of F(x) as follows:

[tex]F(x)=y[/tex]

i.e.

[tex]\dfrac{19}{x^3}=y[/tex]

Now we interchange x and y

i.e.

[tex]\dfrac{19}{y^3}=x[/tex]

Now we solve for y as follows:

[tex]y^3=\dfrac{19}{x}\\\\i.e.\\\\y=\sqrt[3]{\dfrac{19}{x}}[/tex]

      Hence, the inverse function is:

                 [tex]\sqrt[3]{\dfrac{19}{x}}[/tex]

To ensure the cost doesn't exceed $49, the chemistry club can rent the meeting room for fewer than 7 hours.

The subject is Mathematics, and it's likely for High School level. This problem deals with the concept of linear inequalities. Here, the total cost of renting the room is given by the equation:

y = 14 + 5t,  where t represents the number of hours the room is rented. The chemistry club wants to spend less than $49, so we have the inequality: 14 + 5t < 49. Subtract 14 from both sides to get 5t < 35. Finally, divide both sides by 5 to solve for t, ending up with: t < 7. Therefore, the chemistry club could rent the meeting room for fewer than 7 hours to keep the cost under $49.

Answer:

If not, stop and use Steps for Solving an Exponential Equation with Different Bases. Step 2: Rewrite the problem using the same base. Step 3: Use the properties of exponents to simplify the problem. Step 4: Once the bases are the same, drop the bases and set the exponents equal to each other.

Answer:

This ordered pair is NOT a solution of the equation.

Step-by-step explanation:

First, it is important to note that ordered pairs consist of (x, y) so in this case

x = 15 and y = -3.  And that any variable directly next to a number calls for multiplication.  So, plugging in the variables the equation would look like

"-3 = 5 x 15"  

To see if 5 x 15 = -3 we will multiply them.  5 x 15 actually equals 75 not -3.  So we know this ordered pair is NOT the solution for the problem.

Step-by-step explanation:

What you do to figure this out is you take the 3^15 and make it to where there is 15 3's.

3, 3, 3, 3, 3, 3, 3, 3, 3 ,3, 3, 3 ,3, 3, 3.

You will then put them in groups of 2 to get them out of the Square root.

3,3    3,3    3,3    3,3    3,3    3,3    3,3    3.

There are 7 groups where the 3 can come out of the Square root.

So your answer is 3^7sqrt3. D is your answer.

Answer:

d. 3⁷√3

Step-by-step explanation:

√(3¹⁵) can be written as √(3¹⁴ₓ 3)

=√(3¹⁴)ₓ√3

To find the the square root of the number in index form, we divide the index by 2.

√(3¹⁴)=3⁷

let √3 remain in surd form, then we shall have the solution as 3⁷×√3

=3⁷√3

it is 4 1/2 inches long

The right end of the board lines up with the mark halfway between 4 and 5, which means the mark is at 4.5 inches.

Since the board ends at the mark, the length of the board is 4.5 inches.

The length of the board in the image is 4.5 inches.

We can determine this by looking at the scale on the ruler in the image. The scale is marked in inches, and the right end of the board lines up with the mark halfway between 4 and 5.

This means that the mark is at 4.5 inches, and since the board ends at the mark, the length of the board is 4.5 inches.

Another way to think about this is to imagine that you are measuring the board with a ruler.

If you place the ruler at the left end of the board and line up the zero mark with the left end of the board, then the right end of the board will be at the 4.5-inch mark on the ruler.

Here is a more creative way to answer your question:

The board in the image is 4.5 inches long, or as long as a half-dollar coin laid on its side.

Imagine that you have a half-dollar coin. If you place the coin on its side next to the board, you will see that the coin is exactly the same length as the board. This is a fun and easy way to remember the length of the board without having to use a ruler.

Hello :)

Sorry I cant draw a graph on here but I can explain this to you. So if you have a calculator on you (a scientific one) you can use the table mode by pressing mode and then table. If you do not have a calculator then the axis on the graph you have needs to be substituted where x is.

If the axis is from -3 to 3 you need to enter every single value from -3 to 3 and substitute where x is

EG - (-3)^2-6(-3)+5 that is 32

Keep following for the rest of the values (it depends on your scale)

In this case we have

32,21,12,5,0,-3,-4 these each correspond and these are values on the y axis.

These each correspond to -3,-2,-1,0,1,2,3 in this exact order.

Plot the Graph with the values from this so on the x axis you will have -3 and on the y axis you will have 32 and so on.

This allows you to plot your graph

Answer:

Step-by-step explanation:

We can factor the equation to find the zeros

y = x^2 − 6x + 5

0 =   x^2 − 6x + 5

0 = (x-5) (x-1)

Using the zero product property

x-5 = 0      x-1 =0

x=5   x=1

The zeros are at (1,0) and (5,0)

The vertex is 1/2 way between the zeros

1+5 = 6  6/2 =3

The x coordinate of the vertex is 3

Substituting into the equation

y = 3^2 -6(3) +5

y = 9-18+5

y= -4

The vertex is at (3,-4)

We know it is symmetric around x=3

The y intercept is (0,5)

4(x + 3) = 9x + 16 + 3x

Distribute the 4

4x +12 = 9x+16+3x

Combine like terms

4x+12 = 12x+16

Subtract 4x

4x-4x+12 = 12x-4x+16

12 = 8x+16

Subtract 16

12-16 = 8x+16-16

-4 =8x

Divide by 8

-4/8 =8x/8

Surface Area = 471.2 cm^2

Surface Area = 60.75 m^2

Step-by-step explanation:

The surface area formula for a cylinder is π x diameter x (diameter / 2 + height), where (diameter / 2) is the radius of the base (d = 2 x r), so another way to write it is π x radius x 2 x (radius + height). ( π =3.14 )

FORMULA:

π x 5 x 2 x 15

WORK:

π x 5 = 15.7

15.7 x 2 = 31.4

31.4 x 15 = 471

The surface area formula for a triangular prism is 2 * (height x base / 2) + length x width1 + length x width2 + length x base.

WORK:

(2.5 x 1.5) = 3.75/2 = 1.875

1.875 x 2 = 3.75

(6 x 4) = 24

(6 x 4) = 24

(6 x 1.5) = 9

Answer:

$22554.45

Step-by-step explanation:

Since we are given a function to use to find the cost of the car, we first need to find the difference in the years 2017 and 2010

2017 - 2010 = 7

So our value for t will be 7.

We can use the formula because it still falls under the expected increase within the 10 year range.

So now let's substitute t in the function.

[tex]f(7) = 15000*(1.06)^{7}[/tex]

[tex]f(7) = 22554.45[/tex]

So it will cost the company $22554.45 to build the car in 2017.

The cost to build the car in 2017 is $22,554.45.

1. Identify the given function:

[tex]\[ f(t) = 15000 \times (1.06)^t \][/tex]

2. Substitute [tex]\( t = 7 \)[/tex] into the function:

[tex]\[ f(7) = 15000 \times (1.06)^7 \][/tex]

3. Calculate [tex]\( (1.06)^7 \):[/tex]

[tex]\[ (1.06)^7 \approx 1.50363 \][/tex]

4. Multiply by the initial cost:

[tex]\[ f(7) = 15000 \times 1.50363 \approx 22554.45 \][/tex]

To find the equation of a line that is perpendicular to another line, we need to consider the fact that perpendicular lines have slopes that are negative reciprocals of each other. The given line has a slope of 1, so the perpendicular line will have a slope of -1. Using the point-slope form of a line, we can find the equation of the perpendicular line by plugging in the given point and slope.

To find the equation of a line that is perpendicular to another line, we need to consider the fact that perpendicular lines have slopes that are negative reciprocals of each other. The given line has a slope of 1, so the perpendicular line will have a slope of -1.

Using the point-slope form of a line, y - y1 = m(x - x1), we can plug in the values of the given point (-12, 10) and the slope (-1) to find the equation:

y - 10 = -1(x - (-12))

y - 10 = -1(x + 12)

y - 10 = -x - 12

y = -x - 2

Therefore, the equation of the line that is perpendicular to y = x - 2 and passes through the point (-12, 10) is y = -x - 2.

Step-by-step explanation:

x2=400

x=√400

=20

20^2=400

The solutions to the equation x² = 400 are x = 20 and x = -20, obtained by taking the positive and negative square roots.

The given equation is x² = 400. This is a simple quadratic equation, and we can solve it by taking the square root of both sides. Any positive number n has two square roots: positive root √n and negative root -√n. So this results in two equations: x = √400 and x = -√400.

Solving these, we find that x = 20 and x = -20. So, the solutions to the equation x² = 400 are x = 20 and x = -20.

Answer:

1/25

Step-by-step explanation:

Total number of DVD's in the box = 20

Number of defective DVD's = 4

The probability of picking up a defective DVD = [tex]\frac{4}{20}=\frac{1}{5}[/tex]

This DVD is being replaced back. So this does not change the total number of DVD's in the box and the number of defective DVD's in the box.

So again the probability of picking up the second defective DVD = [tex]\frac{4}{20}=\frac{1}{5}[/tex]

The probability that both DVD's are defective will be the product of probabilities of individual events i.e.

[tex]\frac{1}{5} \times \frac{1}{5}  = \frac{1}{25}[/tex]

Thus, the probability that both DVDs are defective is 1/25

The probability of selecting two defective DVDs from a box containing 20 DVDs with 4 defective ones, with replacement, is 1/25.

To find the probability that both DVDs are defective, we need to consider the probability of selecting a defective DVD on each trial.

Since the DVDs are selected with replacement, the probability remains constant.

There are 20 DVDs in total, with 4 of them being defective.

So the probability of selecting a defective DVD on the first trial is 4/20 = 1/5.

Similarly, the probability of selecting a defective DVD on the second trial is also 1/5.

To find the probability that both DVDs are defective, we multiply these probabilities together:

Probability = (1/5) * (1/5) = 1/25

Answer:

theyre both the same rate.

A:

Substitute

7(1) - 2(5) = -5

Multiply the number inside the parentheses by the number outside.

7 - 10 = -5

Subtract the numbers.

-3 = -5

This is not the solution to the equation because the numbers on both sides don't equal to each other.

B:

Substitute

7(-1) - 2(1) = -5

Multiply the number inside the parentheses by the number outside.

-7 - 2 = -5

Subtract the numbers.

-9 = -5

This also not the solution to the equation because the numbers on both sides don't equal to each other.

C:

They both are not the solution to the equation because the numbers on both sides don't equal.
